I don't know if he is alive. If the qi is yang, the yang goes one inch and the yin goes one inch. If Yang stops for a while, Yin will also stop for a while, so we can know that Yang is the master of Yin. Yang Qi cycle, Yin Qi has no stagnation, and naturally it can't afford all diseases. Yang deficiency, slight stagnation, and many diseases.

-"The True Story of Medicine" (Zheng Qinan, a famous doctor and founder of Vulcan religion in the late Qing Dynasty)

Fuyangtang, a well-known health chain organization, was founded and popularized by Mr. Yu Daohui, the author of the best-selling book "Keeping Health, Nourishing Yang Qi First". Professional, authoritative and personalized conditioning function is the first choice for people with various health problems. The company takes "helping Yang Qi, removing polluted air, recovering healthily and naturally" as its core health preserving concept, and "professionalism, authority and individuality" as its business philosophy.

The word "Yang" in Fuyang Hall means "Yang", not "Yin and Yang". What is Yang? Yang Qi, function also. Simply put, Yang is the general name of the function of human viscera and the fundamental motive force of human life activities. Its main concept is similar to the "metabolism" of the human body in modern medicine. Different zang-fu organs have different corresponding zang-fu functions, such as the zang-fu function of the heart, which is called heart yang in traditional Chinese medicine; The viscera function of kidney is kidney yang in traditional Chinese medicine.

The theory of Yin and Yang is only a philosophical concept, not a concrete thing, but a unique clinical thinking of Chinese medicine doctors. To put it more simply, the theory of yin and yang is just a way for us to look at problems, that is, "things should be treated in two." Yang in TCM is a concrete thing, that is, function. The only difference from modern medicine is that the name is different. Chinese medicine is called yang, while western medicine is called function. The other side corresponding to Yang Qi is yin essence, which is the essence of modern medicine. Yang qi and yin essence are tangible, not mysterious things, and their relationship is the relationship between Yin and Yang in the theory of Yin and Yang. For thousands of years, because people have confused this concept, Chinese medicine has been brought into a mysterious and superstitious situation.
